Table 1.

Ca2+ dependence of neurotransmitter release evoked by different secretogogues. Data shown as mean (sd) (n). Ca2+ dependence was determined as the percentage of the mean normalized sum ΔFR in the absence of Ca2+ compared to that in the presence of Ca2+. ND, not determined. *P<0.05, ***P<0.001 vs glutamate; †††P<0.001 vs GABA; ‡‡‡ P<0.001 vs norepinephrine, by one-way anova with the Tukey post hoc test
